Conditions For Setting DTC

Engine is operating in closed loop.
Engine coolant temperature is more than 140°F (60°C).
Engine has been running at least one minute.
Canister purge duty cycle is 10 percent or more.
Engine speed is between 1500 and 3000 RPM.
Mass air flow is between 8 and 42 g/s.
Above conditions are present for 3 seconds.
90 seconds after closed loop and stoichiometric operation have been enabled, the PCM monitors the oxygen sensor switching above and below 450 mV. If fewer than 29 rich-to-lean and lean-to-rich switches for Bank 2 HO2S 1 are detected, DTC P1153 will set.
